Explanation for Question 50 From the Reading Section on the 2019 May Sat
Question 50 asks, which choice best supports the idea that the migration of brine 2 shrimp may not have the effect suggested by Dewberry and Wilhelmina. 3 So let's look at the lines of evidence given to us here as answer 4 choices and see which one best supports this idea. 5 So the migration of ship may not have the suggested effect. 6 So let's start with answer choice a it says, 7 I wouldn't want to say just yet. The bio mixing is important at a 8 global scale solely based on a lot of experiments. 9 So Steven Maness Smith, a fluid mechanism at Stanford university. 10 So looking at answer choice a, it doesn't really give us any specific information 11 on the migration or the effect of the migration of Brian shrimp. 12 And so it wouldn't really support the idea that we're looking to support here. 13 So answer choice a would be incorrect. If we look at answer choice B, 14 it says most of the energy from the shrimp probably goes into heating the 15 water rather than mixing it. 16 He says, so in this case, we see a bit of a reference to 17 the effect that this migration might have, 18 right? They're either going to be mixing it here or heating the water. 19 And so those are kind of the two effects. And we can see earlier 20 in the passage that the theory produced by Dewberry and 21 is that their energy will go to mixing the water. 22 So in this case, what the scientist is saying that instead of mixing 23 it, it probably goes to heating it. So you can see that this is 24 kind of c...
